Answer:

A. Melting

Explanation:

In the above question we noticed that there is a passage from a regular and well compacted carbon dioxide molecules to molecules in a less compact and lower density pattern after a period of heating. According to this description we can conclude that a physical process called "Melting" occurred, which is the process, where a solid substance (which has very compacted molecules) when heated becomes a liquid substance, with less compacted molecules and lower density.

Melting explains the changeover from heating to solid state to liquid state. Heating causes the temperature of the substance to rise to its melting point. The temperature does not rise while fusion is taking place, that is, only after all the substance has gone into liquid state does the temperature rise again.

The melting point of a substance is the temperature at which that substance changes from solid to liquid state.

How can forgery be used in crime
Tems11 [23]

Some bad people will tend to forge dollar bills and make fake bills, giving them to cashiers and asking for it to be split into a different amount of bills so they are given real cash and wont be caught or they will buy things, return them and be given back real money and get away with it. This is obviously a crime because it's fake.
